摘要: There is provided a method for making a wafer comprising the steps of providing a substrate having a first surface, an opposite second surface, and at least one side edge defining a thickness of the substrate, the at least one side edge having a first peripheral region and a second peripheral region adjacent to the first peripheral region. The method includes applying a fluid to the first surface and the first peripheral region of the at least one side edge and removing the opposite second surface and the second peripheral region of the at least one side edge to form a third surface. A semiconductor chip made from the method for making the wafer is also provided.

摘要: A method of selectively tailoring the slope of via hole sidewalls. A first polyimide layer (in which the vias are to be formed) is covered by a strippable layer, and the two layers are isotropically etched. By varying the thickness of the strippable layer with respect to that of the polyimide layer, the slope of the via hole sidewalls can be controlled.
